Description
Technical Field
The invention relates to the field of textile machinery, in particular to a transport system of a can.
Background
It is known that there are currently typically 4 spinning processes: ordinary ring spinning, combed compact ring spinning, rotor spinning and vortex spinning processes. In these processes, the slivers are stored and transported by cans between the carding machine and the drawing frame, between the drawing frame and the sliver lap combination machine, between the combing machine and the drawing frame, between the drawing frame and the roving frame, between the drawing frame and the drawing frame, between the drawing frame and the rotor frame, between the drawing frame and the vortex frame; and these cans are typically manually transported by an operator. Another bottleneck is that the slivers of the can are exchanged or the slivers are broken during the creel of the drawing frame, sliver lap combiner and creel of the roving frame, and all these piecing operations still need to be performed manually. These can handling splices including slivers greatly increases the labor load of the operating workers and also restricts the implementation of unmanned factories in spinning mills.
To address this situation, many industry practitioners are actively engaged in research and development efforts, including the use of AGV vehicles.
For example, invention 201710002750.6, provides a method for transporting a can using an AGV cart: the operator needs to push the AGV to a position near the transported object, then turns on a power switch, and sucks the object through the suction effect of a vacuum pump, so that the workload of the operator is reduced. The invention has the following disadvantages: the sliver can has no electronic tag, and the AGV car, the sliver can and each process have no communication, so that intelligent transportation can not be realized.
For example, invention 201811202662.1 proposes a method for manufacturing electronic label of can, which is used to solve the problem of tracing back from a certain spindle cop defect of spinning frame to the corresponding can strand. The invention only provides a manufacturing method of the electronic label, and does not relate to the function of the electronic label in automatic barrel transportation.
For example, invention 201910423345.0 discloses a cotton spinning logistics system, which is used for transporting slivers from a carding machine to a roving machine in a ring spinning factory by means of an AGV and a fixed rail. The invention has the disadvantages that the logistics system is only used in a ring spinning process, the transport of the cans only partially uses an AGV (automatic guided vehicle), the cans are only input into each rail, and the cans are still transported to each guide bar rack on the rails according to a fixed route; the cans used also do not have electronic tags, so there is no communication between the AGV cars and the equipment and cans for each process.
